Abstract (en)

The invention relates to a wireless access telecommunications system comprising at least one SA-cell and a plurality of LA-cells. A method for a terminal to facilitate selection of an LA-cell to camp on when in an idle mode is disclosed. The method includes steps of, while the terminal is in an active mode having a wireless connection with the SA-cell, the terminal obtaining, via the wireless connection with the SA-cell, a set of configuration parameters of one or more LA-cells of the plurality of the LA-cells that are relevant for the SA-cell and selecting, out of the one or more LA-cells, one LA-cell to camp on, where the selection is performed based on the received set of the configuration parameters. In this manner, the terminal may select a suitable LA-cell to camp on in a manner that is quick and energy-efficient.
